May not request pain medicine but instead thank Allah for pain

Muslims must seek pain relief when necessary because needless pain and suffering are frowned upon

It's almost like different people are different and busting out the calipers to decide which approach to pain each individual would like to take (instead of, for example, asking them) makes no sense. How can someone read these two clearly contradictory sentences almost back to back and have any faith that what they're reading makes any sense?
